We are deploying Cisco 9124s vertically on poles. I read that Cisco recommends using solar shield in outdoor deployments in direct sunlight, but in the installation documentation, the deployments it shows using the solar shield horizontally to shade the fins of the heat sink. It does not show any solar shield on the vertical deployments (i.e. with the paintable cover). So my question is, do any of you have experience deploying 9124s vertically on poles? If so, did you use a solar shield, or is it in fact designed to shade the heat sink fins on horizontal deployments with the L bracket as we suspect?
Solved! Go to Solution.
When the 9124 was launched I remember Cisco saying it was already sun rated so did not require a solar shield.
The specs: Operating temperature -40 C to 65 C (55 C with solar loading).
But that said, the installation guide still recommends it so probably better to use it.
